Pyrotek Noise Control installed a unique noise barrier solution to resolve a noise problem in the office block of a prestigious building complex in Jakarta.
Kuningan City is a one-stop living solutions complex, located in the central business district of Jakarta. A creation of the Agung Podomoro Group, a large developer in Indonesia, the complex comprises of a shopping centre, office tower, apartments and a multipurpose hall.
Lack of false ceilings in each level of the office tower left the air conditioning ducting visible, exposing the occupants to noise, which increased correspondingly with the increased demand on the air conditioning system.
A leading Jakarta-based insurance company, which occupied the offices found it difficult to function in the noisy environment.
When approached to find a solution, Pyrotek measured the noise levels at up to 61dBA under the ducting elbow, significantly above the acceptable Equivalent Sound Level - Leq for working accommodation of 50dBA. Soundlag 4525C was considered to be the most effective way to reduce the noise.
Featuring a multi-layer construction, the noise barrier is able to act independently to the surface that it’s applied, giving broad-range noise reduction. The flexibility of the noise barrier allows easy installation.
The lagging was fitted, paying particular attention to bends in the ductwork and securely taping the overlaps at joins.
Following installation, the noise readings measured 51-52dBA, down 10dBa from the original measurement. Pyrotek will continue to work with the developer to provide a comfortable and productive work environment for office occupants.
